Abstract
An extrusion die for externally ribbed seamless plastic tubing, including an extrusion head (1) with an elongate nozzle (2) within which a hollow mandrel (3) is placed. The nozzle (2) and mandrel (3) define an annular extrusion orifice forming a parison of the tubing and having a coaxial conical portion with its generatrix forming an angle of substantially more than 45'' with the longitudinal axis of the head (1), the diameter of the mandrel (3) at its delivery end being not less than that of the nozzle (2). The die can be supplied also with an electrical heater incorporated inside the mandrel (3) after said orifice, with a centering means mounting said nozzle (2) uniformly spaced around the mandrel (3), with a threaded member (6) for adjusting longitudinally said mandrel (3) to vary the size of the extrusion orifice, and with a coupling means interconnecting said mandrel (3) and the head (1) and allowing only the axial, without rotation, movement of the mandrel (3).
